Specification of Letters Patent. Patented N 13, 1917 Application filed January 18, 1916. Serial No. 72,838.

To all whom it may concern Be it known that we, JAMES RANDOLPH GREENWOOD BRIERCLIFFE and GEORGE Crus- NALL, subjects of the King of Great Britain, and residents of Farnworth S. 0., in the county of Lancaster, England, have invented a certain new and useful Improvement in Clearers for Spinning-Machines, of which the following description, having reference to the accompanying sheets of drawings, is a specification.

Our invention relates to improvements in or appertaining to clearers for the rollers of preparing, spinning and like machines of the type in which a board is reciprocated over the surfaces of the rollers to be cleaned, and our present improvement consists in means for giving such traverse to said board by separate mechanism or by combining a rotary and an oscillatory clearer whereby the rotary part reciprocates the other portion.

Figure 1 is a sectional end elevation of the rollers of a drawing frame, showing the application of our improved clearers to the upper rollers thereof.

Fig. 2 is a plan of parts shown by Fig. 1.

Fig. 3 is a similar view to Fig. 1 and illustrates our improvements applied to the lower rollers of the machine.

Fig. 1 is a plan of the parts shown by Fig. 3, except that the upper rolls are omitted from Fig. 1.

Fig. 5 is an end elevation showing another modified form of our invention.

Fig. 6 is a similar view to Fig. 3, illustrating a further modification of our im provements.

Fig. 7 is a plan of the combined clearer illustrated by Fig. 6.

Fig. 8 is a sectional end elevation of the rollers of a spinning machine having our improvements applied to the lower series thereof.

Fig. 9 is a plan of the improved combined clearer illustrated by Fig. 8.

Similar letters and figures of reference indicate like parts throughout the several views.

In all the drawings above referred to certain parts of the framework supporting the drawing and spinning rollers are omitted for the sake of clearness. A indicates'the upper series of drawing or spinning rollers and B the lower series thereof.

In carrying our invention into effect we arrange a roller a (which preferably has its surface covered with flannel or similar substance) to rest by gravity, or to be slightly pressed by being weighted or by springs, upon the surfaces of the two rear rollers of the upper series A, while as said rollers A are rotated in the direction indicated by the arrows, said covered roller a will be rotated and will clean the surfaces of said rear rollers. Resting upon the surfaces of the two front rollers of theseries A we have a board Z) with its lower surface faced with flannel or the like, and to this board 6 are attached uprights b at each side thereof, these uprights b lying in the path of motion of the pegs or crank pins 0 mounted at each end of the clearer a. It will be seen that as the clearer a is rotated by frictional contact as above-described, the crank pins 0 will move the uprights b and so traverse the clearer 7) over. the upper surfaces of the series of rollers A, thus to clean said surfaces or remove therefrom any dirtor objectionable matter, said uprights Z)- being pressed against the crank pins 0 throughout the extent of the rotary movements of the latter by the friction of the rollers A against the lower surface of the clearer Z), while the rear edge 6 of said clearer Z) will assist in cleaning or clearing the surface of the roller A during the time that same is resting in contact therewith.

The downwardly projecting lips b at the front of the clearer 7) limit the rearward movement of said clearer, by which means the crank pins 0 may traverse through. a portion of their rotary movements without operating said clearer Z), and in order that the extent of the movement of the latter may be varied, we may arrange the uprights b to be adjustable relatively to the other parts of the clearer. The lateral movement of the clearer b is controlled or prevented by the edges 6 taking over the'ends of the fluted parts of the rollers A or upon the reduced portions A of said rollers 'A. Flanges a are also arranged on the clearer a for the same purpose.

WVe find, in cases where the clearer a is ro tated by resting on the surfaces of the rollers A by gravity, that when in the'position indicated by Fig. 1, the frictional contact thereof is not great enough to perform the reciprocation of the clearer 6 against the frictional contact of-its lower surface upon the front rollers A, and to overcome this, we embed in the clearer a plugs or weights of lead or the like (6 these plugs being arranged eccentrically relatively to the axis of the clearer a, such plugs (4 increasing the grip of the surface of said clearer a upon said rollers A. The exposed ends of the plugs are flush with the surface of the rolls. lVe preferably make use of a handle 0 by which the clearer Z) may be move-d, and by forming same hollow and placing therein different amounts of granulated or like substances such as shot, we may vary the friction between the surface of the clearer b and the rollers A. We can at any time during the operations of the machine remove the of cleaning or repairs.

In Figs. 3 and 4 we have shown a combined revolving and reciprocating clearer for the lower rollers, the rotary portion a driving or reciprocating the other part Z) in a manner somewhat similar to that hereinbefore described. The clearer a is supported in frictional contact with the two rear rollers of the series B by means of the weights (Z and cords d, the latter of which pass over reduced portions of the roller B The clearer Z) is supported by the weights f and cords the latter of which take over reduced portions of the roller B On the ends of the clearer a we form or mount cams or scrolls a which make contact with and operate the projecting parts 79 mounteo or formed upon the clearer b, said parts b 'being pressed against the cams a -by the frictional contact of the surfaces of the two front rollers B with that of the clearer b. The roller B is usually smaller in diameter than the other rollers of the same series, hence we form a raised part b on the clearer Z) to make contact therewith.

Fig. 5 illustrates a slight modification of the means for reciprocating the clearer shown by Figs. 3 and i, in this case eccentrics a being employed instead of the cams a In Fig. 6 crank pins 0, are made use of and these in their rotations operate links 9 which are connected by the pins g to the clearer b, the reciprocations of said clearer being similar to those hereinafter described. In connection with these under clearers, the rear end thereof assists in cleaning the sur face of the rollers B in a similar manner to the cleaning of the roller A by the top clearer 5 shown in Fig. 1. The clearer a in Fig. 6 is supported by weights a and cords clearers a and Z) separately for the purpose Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.-

03 the cords passing over reduced portions of the roller B and being attached to links g.

In Fig. 8 the clearer a has crank pins fixed in its ends, these being connected to the clearer b by means of the eye bolts a in order that the clearer a will by its rotations, reciprocate the clearer Z) over the surface of the front roller 13. In this case, we have the clearers a and b positively connected together, so that the weights 7 and cords 7'" will support both the said clearers a and Z), while the latter is positively operated or moved over the rollers B in both directions.

Such being the nature of our said invention, what we claim is 7 1. In connection with the rollers of spinning machines, a clearer roller for contact with certain of said rollers, a reciprocatory clearer for contact with the surfaces of said 7 rollers, and a connection between the two clearers whereby the rotating clearer drives the reciprocatory clearer.

2. In connection with the rollers of spinning machines, a rotary clearer for contact 4. In connection with the rollers of spinning machines, a rotary clearer for contact with certain of the rollers, a reciprocatory clearer for contact with certain other rollers, and a connection between the two clearers whereby the reciprocatory clearer is driven positively in both directions by the rotary clearer.

5. In connection with the rollers of spinning machines, a rotary clearer resting by gravity upon and being rotated by certain of said rollers, a reciprocatory clearer resting upon certain other'rollers, a connection between said rotary and reciprocatory clean ers, and means for weighting said rotary clearer.
